You could cannibalize some Linux desktop installs.
But it will never be The Year of the *nix on Everyone's Desktop until you get devs and UI people who actually have any idea how normal clueless users work (or even care) and completely shelter them from the *nix underneath. That's anathema to normal *nix devs, so it would take someone like Apple to do it again. But even there almost no OSX users have any clue they're using BSD, and the giving is all one way -> BSD to Apple. Is it really The Year of BSD on the Desktop when nobody knows or cares? If so, it's already here.
It's a pride thing. You want to think that because your OS is so superior under the covers that everyone should be using it and it'll get more of the press it deserves. So you want everyone using it as their desktop and knowing they're doing so, even Mom or your teen kids. But swca dislike that Mom or the kids just want to
So if you want to make a great *nix desktop for yourself, that's great! But thinking you're going to get a random person who thinks the big box is 'the cpu' to use it is just expensive vanity, and has been for almost 20 years. It just leads you to things like Unity.
Besides, even now, five years from 2020, casual users can get everything they need from mobile or web already.
